Definitions

  • This invention relates to an electric telehandler; in detail, the invention relates to a telehandler which can be either hybrid or "full-electric", that is to say, completely electric.
  • Telehandlers consisting of a vehicle equipped with a movable frame on wheels, a driver's cab and an operating arm which can be extended telescopically.
  • an apparatus for lifting and/or moving loads such as, for example, a fork, a cage, a lateral transfer unit, a hoist, etc.
  • telehandlers are equipped with an internal combustion engine A, of the diesel type, which drives a hydrostatic pump B which controls a hydrostatic motor C acting on one of the differentials D1, which is in turn connected to the other differential D2 by means of a Cardan shaft E, so as to rotate the four wheels R on which the vehicle is moved (see diagram in Figure 1 ).
  • the same hydrostatic pump B controls the drive F for actuating the hydraulic distributor G, which in turn drives the cylinders which produce the movements, for example of the arm, of the apparatus, etc.
  • electro-hydraulic telehandlers have been developed, equipped with an internal combustion engine, an electric motor, powered by a battery and a hydrostatic transmission.

  • the invention can comprise the use of gears 9, for example with two ratios, designed to allow the connection between elative electric motors and the axles 51, 52.
  • the gears 9 can be flanged directly on the axles 51, 52, as shown in Figures 3 , 4 , 5 , 7 , 8 and 9 , or, according to a version not illustrated, they can be positioned in line with and connected to the axles by means of two relative Cardan joints.
  • the traction apparatuses comprise a kinematic mechanism for connecting between the electric traction motor 4, 41, 43, 44 and the wheels 3, it is possible to provide a gear motor for the connection between the above-mentioned motor and the mechanics of the relative traction apparatus.

  • an external energy source such as, for example, the electricity network.
  • the battery pack 7 (or the packs 7, 7') of this and the other embodiments and versions of the invention can be of the lithium iron phosphate type, which is particularly suitable for this application, where the operating temperatures are sometimes quite high, since they are batteries with a very low risk of fire or explosion.
  • FIG. 4 , 7 , 8 and 9 which is similar but not identical to the first, there are two electric motors 41, 42, of which a first motor 41 is connected to a traction apparatus 3, 51, whilst a second motor 42 is connected to the pump 21 of the movement means.
  • the coupling device 6 provided in the first embodiment is not necessary and the first motor 41 is connected directly to one of the two axles 51, 52, which are always joined by the Cardan shaft 53.

  • the telehandler 1 includes at least two battery packs 7, 7' both connected to the two electric motors 41, 42.
  • the telehandler 1 does not have a cab or is in any case designed to be transported with a self-powered truck or similar between the place of work and the storage site, it is not necessary to have more than one battery pack 7, although a plurality of packs 7, 7' is certainly not a drawback.
  • the telehandler 1 is equipped at the height of the carriage, that is to say, of the frame carried by the wheels which supports the arm 11, the tower 10 and/or the cab, with external electrical sockets, connected to the batteries 7, 7', for supplying power to external users, such as, for example, work tools (drills, screwdrivers, demolition hammers, etc.).
  • the battery packs 7, 7' of all the embodiments and versions of the invention can be recharged by means of the electricity network, in the so-called “plug in” manner, even though this feature has been schematically illustrated only in Figures 7 , 8 and 9 , for simplicity of description.
  • the battery pack 7 is connected to an internal combustion engine 8, preferably but not exclusively a diesel engine, for example of the so-called "stage 5" type.
  • the internal combustion engine 8 is designed exclusively for charging the battery 7 (or batteries 7, 7') or battery packs 7, 7'.
  • the internal combustion engine 8 is equipped with a tank for the fuel and is set up, by use of a generator, for recharging the battery 7.
  • This hybrid configuration allows the autonomy of the telehandler 1 to be increased, allowing it, for example, to increase road travel.
  • the internal combustion engine 8 is housed in a container or "drawer" which can be extracted and closed in a concealed fashion by/in the carriage of the telehandler 1, to facilitate the maintenance; alternatively, the engine can be accessible by means of a hatch formed in the bonnet of the carriage.

  • the internal combustion engine 8 is used exclusively for charging batteries and is disconnected from the electric motors 41, 42.
  • the invention can include a control unit configured to automatically control the actuation of the recharging internal combustion engine 8, if it detects that the charge contained in the batteries 7, 7' has dropped below a predetermined threshold.
  • the invention comprises two electric motors 43, 44 for moving the two traction apparatuses 3, 52, 52, each connected directly to a respective axle 51, 52, as shown schematically in Figure 5 .
  • an electric motor 45 is used dedicated to the movement means 2, 21, connected directly to the pump 21 which supplies the distributor 2.
